Unless the equation has an aqueous compound in it, there is no net ionic equation.
CaCO3 ====CO2+ CaO
becouse its not in an aqueous solution no net ionic is needed you science teacher probably just wants to see if know when to use net ionic equations
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
Calcium carbonate reacts with methanoic acid to produce calcium methanoate, carbon dioxide, and water. The word equation for this reaction is: calcium carbonate + methanoic acid → calcium methanoate + carbon dioxide + water.
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
A reaction between an acid and a carbonate gives a salt, water and carbon dioxide. So the word equation is: acid + carbonate -----> salt + carbon dioxide + water eg: hydrochloric acid + calcium carbonate ----> calcium chloride + carbon dioxide + water See: http://www.sky-web.net/science/reaction-types.htm
The products are calcium oxide and carbon dioxide The equation: CaCO3 -> CaO + CO2
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
Calcium carbonate heated to form calcium oxide and carbon dioxide as shown by the equation CaCO3(s) → CaO(s) + CO2(g).
Calcium carbonate is heated to from calcium oxide and carbon dioxide as illustrated by the chemical equation CaCO3(s) ===> CaO(s) + CO2(g).
The equation for the thermal decomposition of calcium carbonate into calcium oxide and carbon dioxide is: CaCO3 (s) -> CaO (s) + CO2 (g)
Calcium carbonate reacts with methanoic acid to produce calcium methanoate, carbon dioxide, and water. The word equation for this reaction is: calcium carbonate + methanoic acid → calcium methanoate + carbon dioxide + water.
Calcium carbonate + heat= Calcium oxide + carbon dioxide is the word equation for the endothermic reaction which occurs in lime kiln.
The word equation for the reaction between nitric acid and calcium carbonate is: nitric acid + calcium carbonate → calcium nitrate + carbon dioxide + water.
calcium hydroxide + carbon dioxide = calcium carbonate + water
Calcium Carbonate + Heat ------------ Calcium Oxide + Carbon Dioxide
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
metal carbonate + acid = metal salt + carbon dioxide + water e.g. calcium carbonate + hydrochloric acid = calcium chloride + water + carbon dioxide CaCO3 + 2HCl = CaCl2 + H2O +CO2
Calcium is an element and does not decompose. It can oxidize though.
